For the snug-fit on my DIY APEs I use turns of Frog Tape.
Also use it for temp fixing of cables to stands, taping cables to floors, endless uses; much less money than Gaffer tape. It's high-visibility green color is useful for marking floors around stands. Plus, the lidded box it comes in is handy for storing small parts, etc.
Much sturdier than blue painter's tape; the paper and the adhesive are both stronger, and yet comes off just as clean.
In 1", 1.5" or 2" widths; I keep 1" and 2" on hand.
